I just started playing with HC-05 Bluetooth modules and below are some short videos of projects I built. The first video is a direct copy of a tutorial by Dejan Nedelkovski which using a single potentiometer to control a servo. The second video I modify the project to use 3 potentiometers to control an RGB LED. The 3rd video I use a smartphone to control the RGB LED.

Quote of the day

“I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success... such emotions make a man forget food, sleep, friends, love, everything.“
